Coefficient of Discharge when Outflow is Considered Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Discharge = (Reservoir Discharge/((2/3)*sqrt(2*Acceleration due to Gravity)*Effective Length of the Spillway Crest*((Head over Weir^3)/2)))
C_d = (Qh/((2/3)*sqrt(2*g)*L_e*((H^3)/2)))
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Coefficient of Discharge - Coefficient of Discharge is ratio of actual discharge to theoretical discharge.
Reservoir Discharge - (Measured in Cubic Meter per Second) - Reservoir Discharge is the uncontrolled spillway discharge.
Acceleration due to Gravity - (Measured in Meter per Square Second) - Acceleration due to Gravity is acceleration gained by an object because of gravitational force.
Effective Length of the Spillway Crest - (Measured in Meter) - Effective Length of the Spillway Crest is the length used for the discharge passing over a spillway.
Head over Weir - (Measured in Meter) - Head over Weir is the stream or river to raise the water level or divert its flow.

STEP 1: Convert Input(s) to Base Unit

Reservoir Discharge: 131.4 Cubic Meter per Second --> 131.4 Cubic Meter per Second No Conversion Required
Acceleration due to Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
Effective Length of the Spillway Crest: 5 Meter --> 5 Meter No Conversion Required
Head over Weir: 3 Meter --> 3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_d = (Qh/((2/3)*sqrt(2*g)*L_e*((H^3)/2))) --> (131.4/((2/3)*sqrt(2*9.8)*5*((3^3)/2)))

Evaluating ... ...

C_d = 0.659560769120834

STEP 3: Convert Result to Output's Unit

0.659560769120834 --> No Conversion Required

FINAL ANSWER

0.659560769120834 ≈ 0.659561 <-- Coefficient of Discharge
